[Решено] Translations are overwritten by plugin strings

Background of the issue:
I am trying to translate the word 'Notes' in an ACF custom field from English to French. I want it to appear as 'Notes' in French on the front end. The issue can be seen on this page: скрытая ссылка

Symptoms:
Instead of my translation 'Notes', the system displays 'Commentaires', which seems to be a default WooCommerce or WordPress string translation.

Questions:
How do I force my translation to be the priority?
